The Tay Son Rebellion (1771- 1 802) was led by Nguyen Hue (later known as Emperor Quang Trung), one of the most successful military commanders in Vietnam's history, and his brothers Nguyen Nhac and Nguyen Lu - also known as the Tay Son Brothers.

The family is credited with uniting Vietnam and ending a bloody civil war being waged between the nation's rival feudal houses (the Nguyen in the south and the Trinh in the north). The brothers then led an army in defeating the Chinese Qing invaders.

According to Dr. Pham Huu Cong, the museum's vice director, artifacts from the Tay Son period are scarce compared to other periods in Vietnamese history.
